Patented Feb. 12, 1918.

Application filed November 10, 1917. Serial No. 201,330.

To all whom t may concern:

Be it known that I, JOHN F. OKEEFE, a citizen of the United States, anda resident of the city of New York, Long Island City, borough of Queens,in the county of Queens and State of New York, have invented a new andImproved Extensible Form or Distributing Roller for Presses, of whichthe following is a full, clear, and exact description.

This invention relates to printing presses and has to deal moreparticularly with form or distributing rollers, and the invention hasfor its general objects to improve'the construction of rollers so thatthey can be adjustable as to lengthso as to fit different size printingpresses, the roller being so constructed that it can be easily andquickly adjusted without requiring any special skill.

A more specific object of the invention is the provision ofor spindle iscomposed ofadjustable sections telescopically connected so that thelength of the shaft can be varied, and removably applied to the shaft isthe sleeve which carries the facing composition of the roller, which mayvary in length according to the width of the press or according to thework to be done.

W'ith such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention and wherein similar characters of reference indicatecorresponding parts in all the views,

Figure 1 `is a longitudinal section of they,

invention as a distributing roller;

Fig. 2 is a plan view of the stock section of the shaft;.

Fig. 3 is a view of one end of the roller with a journal attachment forconverting the device into a form roller; 4

Fig. -1v is a detail view of one end of the shaft with a fillerinterposed between the journal section and stock section;

Fig. 5 is a view of the inner end of one of the journal sections; and

Fig. 6 is an enlarged fragmentary plan View of the stock section.

Referring to the drawing, 1 designates the stock section which has acentral cylindrical body portion 2 and end portions 3 of reduced aroller in which the shaftdiameter which enter sockets 4 in the journalsections 5. These sections 5 are of the same diameter as the bodyportion 2 of the stock and they constitute together with the stock theshaftof the roller. Fitted over the shaft is a metal tube or sleeve 6 ofany desired length, which carries the rubber facing com. position 7 ofthe roller. The reduced por tions 3 of the central section 1 have spacedthreaded apertures 8 to receive a screw 9 that passes through an opening10 in the inner ends of the outer sections 5. By reason of the pluralityof openings 8 the outer sections 5 can be moved inwardly or outwardly tolengthen or shorten the roller. When they are adjusted outwardly fillers11 may be employed, which are in the form of sleeves that lit over thereduced ends 3 of the stock section 1, such fillers being secured inplace by set-screws 12 which engage in registering apertures 8 of thecentra] section 2. As shown in Fig. 4, the body portion 2 of the stocksection is provided with a lug 13 which is adapted to enter the recess14 in an end section 5 or a recess 15 in the filler 11 when the latteris used.

To facilitate the assembling of the parts the stock section 1 has anindex line 16 and the inner end of each outer section 5 has a notch orline 17, Fig. 5, which, by being brought into registry with the line 16,insures the easy insertion of the fastening screw 9. The outer surfaceof the shaft formed by the central section 1 and outer sections 5 has aline of apertures or depressions 18 spaced a suitable distance apart andinto any of these apertures engage set-screws 19 in the ends of thesleeve 6. In this manner the sleeve can be of any desired length andstill be fastened securely to the shaft. To facilitate the registeringof the set-screw holes of the sleeve with the line of apertures 18, theends of the sleeve may have notches 20 which are adapted to beregistered with an index line 21 on the shaft.

The outer or journal-carrying sections 5 have dtachable journals so asto adapt the roller for use as a distributing roller, as shown in Fig.1, or a form roller, as shown in Fig. 3. The outer end of each section 5is formed with a threaded stud 22 on which is threaded a long journalattachment 23, Fig. 1, or a short journal attachment 24, Fig. 3. Thelong journals 23 move axially in the bearings 25 of the press frame sothat the roller can properly distribute the ink.

rThe journals 24 have shoulders 26 which prevent longitudinal movementof the form roller, Fig. 5, since the journals 24 cannot move back andforth in the bearings 27.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation Willbe readily understood by those skilled in the art to which the inventionappertains, and While I have described the principle of operation, t0-gether with the device which I now consider to be the best embodimentthereof, I desire to have it understood that the device shown is merelyillustrativeand that such changes may be made When desired as fallWithin the scope of the appended claims.-

Having thus described my invention, li claim as new and desire to secureby Letters Patent:

1. A press roller of the class described comprising a shaft composed ofa central seotion and end journal-,carrying sections telescopicallyconnected with the 'central section, a sleeve fitted over the shaft, anda composition facing on the sleeve.

2. A press roller of the class described comprising a shaft .composed ofa central section and end journal-carrying sections telescopicallyconnected with the central section, a sleeve tted over the shaft, a com-Maasai position facing on the sleeve, and removable journals on the endsections.

3. A press roller of 'the class described comprising a shaft composed ofa central portion having reduced ends, journal-carrying sections havingsockets for receiving the ends of the central-section, means forfastening the sections together in different positions of adjustment, asleeve fitted over the sections, a composition facing carried by thesleeve, and means for fastening the sleeve in fixed relation to the saidsections.

4. A roller comprising a shaft composed of a central section havingreduced ends, said reduced ends being provided with a plurality ofspaced, threaded apertures, end journal-carrying sections fitted overthe reduced ends of the central section, a filler in the form of asleeve on the reduced ends of the central section and between the endsections and the middle portion of the central section, set-screwspassing through the end sections and lillers and engaging in the saidthreaded apertures to secure the sections and fillers in place, thefillers and sections having interlockinglugs and recesses, a sleeve ttedover the sections and secured thereto, a facing composition on thesleeve, and a removable journal on each end section.
